20 Claims.

The present invention relates to an irrigation system of a conventionaltype with which has been combined a novel cooling means for cooling aninternal combustion engine, or other engine used in connection with thesystem and forming a part thereof.

The principal object of the invention is to provide, in an irrigationsystem, a cooling means including a cooling coil or equivalentstructure. The fluid in the coil is cooled by the irrigation water.

Another object is to provide a system of irrigation having means forcooling water that is used in the engine which comprises the source ofpower, with supplementary means automatically controlled for directlyfeeding water from the well or other source of water supply into thecooling coil.

Yet another object is to provide in an irrigation system having a motormeans and cooling means therefor, the latter including a heat exchangecoil, an additional means for further cooling the liquid in the heatexchange coil.

Other objects will appear hereinafter throughout the specification.

In the drawings:

Figure 1 is a side elevational view, partly in section of an embodimentof the invention;

Figure 2 is a perspective view partly broken away of the flume, and ofthe cooling coil located therein;

Figure 3 is a detail view partly in section showing the .inlet for thesupplementary cooling cirmeans for attaching the same to the pipeoutlet; and

Figure 4 is a View partly in vertical section of the connection of theoutlet of the pipe shown in Figure 3 into the cooling coil.

It is customary in irrigation systems to provide a source of powerhereinafter referred to as an internal combustion engine for operatingthe pump which conveys the water from a well, or other water source,such as a reservoir, dam, etc., to the flume of the irrigation system.Other types of engines may be used but for illustrative purposes, aninternal combustion engine of the type used in motor cars or trucks isillustrated as a source of power. It will be understood, however, thatother types of engines using gas, gasoline, butane, or other fuels maybe used which employ water cooling systems, such as water jackets, tocool such engines during use.

In the ordinary use of such engines as the source of pumping power forirrigation purposes, the water cooling systems thereof are inadequateSerial No. 388,626

to cool these engines for best operating temperatures. due to the factthat the irrigation engine radiator, by means of the present invention acontinuous supply of cool water from a coil which is in heat exchangerelationship with the water of the is an element.

Referring to the drawings, numeral I0 is an internal combustion enginehaving the usual water jacket, not shown. This engine is provided withan outlet l2 for heated water, that connects to a conduit I4, the exitend l6 of which empties into tank I8. Ordinarily, this end I 6 would beconnected to the automobile radiator, should the engine be used of anautomobile. However, in the present case, the outlet for hot water fromthe water jacket has been connected to the tank 18 as shown in Figure 1.This tank is supported by suitable supports, not shown, on the fiume 20.The tank is provided with an overflow pipe 22. The outlet 24 of the tankis connected to a flexible hose 26 at the upper end thereof, and thelower end is connected to pipe 28 that forms the inlet to the coil 30.Preferably, this coil lies in the bottom of the fiume 20, so that waterwhich passes along the flume is in direct heat exchange contact with thecoil. The outlet pipe 32 from the coil is connected to the engine l0.This engine is provided with a As shown in Figure 1, the source of watercomprises the well 40 having a pipe 42 mounted concentrically therein,and both the Well and the pipe are closed by the top or stock 44.Located in pipe 42 is pump impeller 46, mounted on driven shaft 48. Thisshaft extends through stock 44 and is preferably provided with a bevelgear 50, which latter meshes with gear 52 that is driven by a shaftsection 54. Shaft section 54 forms part of the drive shaft 56, whichfurther consists of central section 58 and shaft section 60. Theseseveral shaft parts are connected to each other by universal joints 62and 64. The shaft section 60 forms part of, or is directly connected to,the crank shaft of engine so as to be driven thereby.

Extending through the well 40 and pipe 42 is outlet pipe 86. This pipemay be of the usual closed type; i. a, circular in cr oss section, or itmay be a", trough'that will lead off; water. which has been elevated byimpeller 46.

A conventional clutch, not shown, may be in,- terposed somewhere in theshaftins, system between the engine and the impeller, so as,t dis'connect the impeller during engine. During the operation of the ortionofthe system above described, cool water is continuously elevated in pipe42 andgis depositedmy, gravity from pipe 66 into flume 2i] and directlyonto coil 39, the coils of which lie longitudinally along a portionthereof. At the same time, water is continuo sly pumped from. they coil.into the; Watenjacket, of, the ,enginean'd, after cooling the n ne u ppe.
